abstract

We propose a model with an $U(1)_{B-L}$ gauge symmetry, in which small neutrino masses, dark matter and the matter-antimatter asymmetry in the Universe can be simultaneously explained. In particular, the neutrino masses are generated radiatively, while the matter-antimatter asymmetry is led by the leptogenesis mechanism, at TeV scale. We also explore allowed regions of the model parameters and discuss some phenomenological effects including lepton flavor violating processes.

Scalar dark matter, Neutrino mass and Leptogenesis in a $\rm U(1)_{B-L}$ model
hep-ph 2019-08 conditional novelty 4.0 of 10

A U(1)B-L model with four anomaly-cancelling fermions can satisfy dark matter relic density and direct detection bounds, neutrino oscillation data, and the observed baryon asymmetry through resonant leptogenesis.
